The Bridgeport Bluefish punched their ticket to the Atlantic League Championship Series with a 3-2 victory Saturday night against the Southern Maryland Blue Crabs in Game 4 of the best-of-five Liberty Division Series.

Danny Putnam’s walk-off RBI double in the bottom of the ninth inning provided a punctuation mark at the end of the series. Read about Game 4 here.

The Bluefish will visit either the Patriots or York Revolution in Wednesday’s series opener. Those teams are playing a decisive Game 5 today for the Freedom Division title.

If the Patriots advance, Game 1 will be held at 7 p.m. at TD Bank Ballpark.

BRIDGEWATER — At the end of a 76-degree night at TD Bank Ballpark, Brian Adams walked off the pitcher’s mound with the chills.

The winningest pitcher in the history of the Somerset Patriots kept the season alive and added to his big-game reputation by dominating the York Revolution for almost eight innings Saturday in a 7-0 victory in Game 4 of the Atlantic League Freedom Division Championship Series.

The win forced a winner-take-all Game 5 at 5 p.m. Sunday in York, Pa., and improved the Patriots’ all-time record to 9-3 when facing playoff elimination.

A crowd of 4,557 fans responded to Adams’ departure with a loud standing ovation, but the praise for his effort did not end there.

“When you talk about stepping up,” Patriots manager Sparky Lyle said, “that’s what it looks like. It was just a masterpiece.”

BRIDGEWATER — The prospect of elimination wasn’t the only thing that the Somerset Patriots needed to stare down Saturday night in order to keep their season alive.

Three longtime adversaries — Ramon Castro, Jose Herrera and John Pachot — in the York Revolution’s dugout also stood as an unnerving sight for fans of the home team in Game 4 of the Atlantic League Freedom Division Championship Series at TD Bank Ballpark.

The three-pronged former nucleus of the Newark Bears has been re-cast in a familiar role opposite the two-time defending league champions.

Castro, who holds a reputation as the biggest Patriot-killer, and Herrera are two of the league’s premier hitters, and Pachot is a highly skilled catcher.

“To their credit, they have been on the other side a lot,” pitcher Casey Cahill said. “They play hard, they plan to win and they play to have fun. We do the same here and I think that’s why in the end, when it matters most, you see familiar faces.”
